An example of natural selection is the red color of a male cardinal. The females of the species choose mates based on the vibran

t colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time? increased variation in the shades of red because the selection pressure has been relieved increased variation in the shades of red because the cardinals try different ways to impress the females decreased variation in the shades of red because no form of the trait is advantageous decreased variation in the shades of red because the only reason for variation was selection pressure

Answer:

Option D, decreased variation in the shades of red because the only reason for variation was selection pressure

Explanation:

Certain factors which make an organism with in its species selective over other which provide an added leap of survival over others.  

Here, red color of male cardinal has only purpose and this purpose is to attract females thereby making themselves a selective species over other male species.  

Now, if somehow females start selecting males on the basis of some other characteristics then it is sure that the variations in the color of male cardinals will gradually slow down and eventually will stop as selective pressure was the only cause of their variation.

Hence, option D is correct

Aleks [24]

Answer:

Edema occurs when blood pressure exceeds the counteracting force of the vascullar walls in the bloodstream, so fluid remains in the spaces surrounding cells and body tissue swells.

Explanation:

The intravascular hydrostatic pressure increases due to an increase in fluids, therefore the vessel walls begin to perceive this increase in pressure in their walls, generating fluid extravasion to areas of lower pressure.

Simora [160]

Answer:

The question lacks options, the options are:

A) 1 out of 16

B) 3 out of 16

C) 6 out of 16

D) 9 out of 16

The answer is 1 out of 16

Explanation:

This is a DIHYBRID cross because it involves two different genes coding for distinct traits. One of the traits will be dominant while the other recessive. Hence, parents that are purebred for opposite forms of the trait means that one parent is homozygous dominant while the other is homozygous recessive. When these two parents cross, they produce F1 offsprings that all possess the dominant trait but heterozygous/hybrids.

When these hybrids are self-crossed, they produce four different combinations of gametes which when crossed using a punnet square will result in F2 offsprings with a 9:3:3:1 phenotypic ratio according to Mendel's observation.

9 represents offsprings that are dominant for both traits

The two 3's represents offsprings that are recessive for one trait and dominant for the other respectively.

1 represents offsprings that are homozygous recessive for both traits.

Hence, 1 out of 16 offsprings will be homozygous recessive for both traits.
